Benefits of technology
The system achieves enhanced carryover performance with low carryover time, reduced power consumption, and a compact footprint, enabling efficient fluid handling and reduced reagent waste in high-pressure applications.
Problems solved by technology
Systems using smaller bore tubing to accomplish this result typically require higher system pressures to deliver the needed flowrates.
Reduced system volume combined with the desire to process samples faster results in low carryover.
To achieve high efficiency in the referenced compact footprint, minimizing time between subsequent usages has become a significant issue.
In addition, large dead spaces can be present for fluid accumulation, which can result in wasted reagent and areas that are difficult to flush.

Embodiment Construction
[0022]Embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. It will be understood that the figures are not necessarily to scale.
[0023]FIG. 1 is a drawing depicting an isometric view of an exemplary low profile miniature solenoid valve system 10 in accordance with embodiments of the present invention. The valve system 10 may include a first solenoid valve component 12 and a second solenoid valve component 14. The individual solenoid valve components 12 and 14 may be mounted to a common valve body 16 to configure the system as a single manifold. The valve system 10 may include any suitable fastening element 18 for mounting the valve system to equipment in a manner suitable for valve operation. The mounting may provide for ready connection to fluid sources and drain passages as would be suitable for any particular application. The individual solenoid valve components 12 a...

A solenoid valve system includes a valve body defining porting for a fluid flow through the valve body, and first and second solenoid valve components attached oppositely to the valve body. Each valve component includes an electromagnetically driven armature with a poppet that moves between a closed position and an open position. The porting defined by the valve body includes first side porting, second side porting, and common porting in fluid communication with an internal common chamber defined by the valve body. When a respective poppet is in the closed position, flow of fluid is blocked between the respective side porting and the common porting, and when the respective poppet is in the open position the poppet permits a flow of fluid between the respective side porting and the common porting through the common chamber.
Description
RELATED APPLICATIONS[0001]This application is a national stage application pursuant to 35 U.S.C. § 371 of PCT / US2017 / 060511 filed on Nov. 8, 2017, which claims the benefit of U.S. Provisional Application No. 62 / 425,198 filed Nov. 22, 2016, the contents of which are incorporated herein by reference.FIELD OF INVENTION[0002]The present invention relates generally to solenoid actuator valves, and more particularly to solenoid actuator valves for use in applications requiring low carryover, least dead volume, smallest internal volume, compact size and a latching function, such as for example in life science, medical, and analytical chemistry applications.BACKGROUND OF THE INVENTION[0003]Low carryover valves are used in a variety of applications. For example, clinical laboratories and hospitals utilize various diagnostic apparatuses to analyze patient medical samples, such as blood, urine, other fluids, and tissues. Because it is desirable for such apparatuses to be as compact as practica...
